pretty simple question. know how use fputcsv() insert row csv inserts @ bottom. there way use insert @ top of csv?

i need add header existing csv file.

any on great.

thanks!

fputcsv() inserts data @ file pointer, can rewind() pointer beginning of file.

rewind($handle); fputcsv($handle, $fields);

alternately, can open file pointer @ beginning:

$handle = fopen('yourfile.csv', 'r+'); fputcsv($handle, $fields);

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
